Courage, conviction and confidence.

I think that kids have a greater capacity for processing things than we give them credit for.

God created man in His own image, says the Bible; philosophers reverse the process: they create God in theirs.

Just because I don't care doesn't mean I don't understand.

Books! I dunno if I ever told you this, but books are the greatest gift one person can give another.

A thought is an idea in transit.

If you can't explain it simply, you don't understand it well enough.

It isn't what we don't know that gives us trouble, it's what we know that ain't so.

If I could explain it to the average person, I wouldn't have been worth the Nobel Prize.

I like poems you can tack all over with a hammer and there are no hollow places.

The whole of science is nothing more than a refinement of everyday thinking.

I cannot teach anybody anything. I can only make them think

The white man is very clever. He came quietly and peaceably with his religion. We were amused at his foolishness and allowed him to stay. Now he has won our brothers, and our clan can no longer act like one. He has put a knife on the things that held us together and we have fallen apart.

Any sufficiently advanced technology is indistinguishable from magic.

All knowledge that the world has ever received comes from the mind; the infinite library of the universe is in our own mind.

It is possible to fly without motors, but not without knowledge and skill.

As we acquire more knowledge, things do not become more comprehensible but more mysterious.

For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.

There is one quality which one must possess to win, and that is definiteness of purpose, the knowledge of what one wants, and a burning desire to possess it.

Technology is just a tool. In terms of getting the kids working together and motivating them, the teacher is the most important.

Education is an admirable thing, but it is well to remember from time to time that nothing that is worth knowing can be taught.
